However I have never seen it to such an extent as here. Walking along the planty I avoid smoking now because I know if I have a cigarette I will be approached by someone (i would say a bum, but just as often it's not) asking me. And I have very often been shouted at by said person for saying no as if I am in the wrong for not giving them a cigarette. And I have not seen that anywhere else.
That's exactly what I've experienced. It's even worse in the summer when you're sitting out in a beer garden. Almost every time I'm trying to enjoy a beer and a smoke somebody walking past asks for a cigarette. That never ever happened to me in the UK or Switzerland.
